Restoration of a volume deficit may be established by goal-directed fluid therapy guided by respiration-related variation in systolic- and pulse pressure (SPV and PPV). Stroke volume index (SVI) serves as a surrogate end-point of a fluid challenge but tissue perfusion itself has not been addressed. %K arterial pulse pressure %K arterial systolic pressure %K cerebrovascular circulation %K fluid therapies %K body fluids %K head-up tilt %K spontaneous breathing %U http://www.frontiersin.org/Journal/10.3389/fphys.2014.00157/abstract
